BACKGROUND OF THE INVENTION

1. FIELD OF THE INVENTION

The present invention relates to a game-medium renting machine for renting game-medium for use in a gaming machine depending on a value subtracted from a value read out by a reader.

2. DESCRIPTION OF THE RELATED ART

In the related art, there has been known a game-medium renting machine for renting a predetermined number of game-media to a gaming machine (such as a slot machine or a pachinko gaming machine) wherein game-media (such as medals or gaming-balls) are used for playing games (as disclosed for instance, in Japanese Patent Application Laid Open Publication No. 2002-143539).

In particular, the conventional game-medium renting machine is located, for instance, between adjacent gaming machines and has an insertion slot for inserting money such as bills and coins. Also, the conventional game-medium renting machine has a structure in which game-media are rented to a player depending on the amount of value (such as game-medium rental fee) subtracted from the amount of money inserted to the insertion slot.

Meanwhile, as one of the feature of the conventional gaming machines, there has been known a “player-saving function” which saves the player by notifying operation procedures for aligning symbols in predetermined pay-lines. More particularly, this function refers the number of game-media being consumed by the player and the number of game-media being paid out for the player, in case where even if the player plays a predetermined number of games without having bonus games (such as BB=Big Bonus, RB=Regular Bonus), the consumed number is greater than the paid out number, and the player's loss reaches a predetermined value, then the player-saving function notifies the player with the operational procedures. By this notifying, the player acknowledges how to align the symbols in the predetermined winning combination.

The gaming machine with such a player-saving function has had a success in providing an entertaining by decreasing the loss of the player.

SUMMARY OF THE INVENTION

However, among the conventional gaming machines, there is a gaming machine with no function to save the player and such a gaming machine encounters issues with a difficulty in reducing the loss of the player.

The present invention has been completed with a view to addressing the above issues and has an object to provide a game-medium renting machine that, even under a situation where a gaming machine has no function to save a player, has a capability of reducing a loss of the player resulting from playing the gaming machine.

To achieve the above object, an aspect of the present invention provides a game-medium renting machine comprising: a reader for reading out a value; game-medium renting unit configured to rent game-medium, for use in a gaming machine, depending on a value subtracted from the value read out by the reader; subtracting unit configured to subtract a first value from the value read out by the reader based on a predetermined operation executed by a player without causing the game-medium to be rented by the game-medium renting unit; and providing unit configured to provide the player with a predetermined value when the first value is subtracted by the subtracting unit and a predetermined condition is established.

With such a feature, under circumstances where the first value is subtracted from the value read out by the reader as the supplemental-value and the predetermined condition is satisfied, the game-medium renting machine is operative to allow the player to be given with the predetermined value whereby, even if the gaming machine has no player-saving function, it becomes possible to reduce the loss of the player caused by playing the gaming machine.

Also, as used herein, the term “predetermined condition” refers to 1) a status where the number of game-media used for the play reaches a predetermined number, 2) a status where the number of consumed game-media, indicative of a difference between the number of game-media used for the play and the number of game-media paid out for the player, reaches a predetermined amount of consumed game-media (when the losing of the player reaches a predetermined number of losing) and 3) a status where the number of times (the number of games) the games are executed by the player reaches a predetermined number of times.

A gaming machine and card unit according to the present invention are not limited to the structures described above with reference to the first embodiment. That is, while with the first embodiment, the payout operation of game-medium (medals) is executed by the game-medium renting machine 200, a third embodiment contemplates the provision of a structure wherein the payout operation of game-medium (payout operation) is performed by the gaming machine 100. Also, the third embodiment is described with reference to a case where the gaming machine 100 is comprised of a pachinko gaming machine wherein the game-medium renting machine 200 reads out an outstanding balance of a prepaid card.

Hereunder, referring to FIG. 6, description is made of the gaming machine 100 and the game-medium renting machine 200 of the third embodiment according to the present invention.

As shown in FIG. 6, in step 50, the game-medium renting machine 200 reads out an outstanding balance of a prepaid card inserted to a card insertion slot by a player.

In step 51, the game-medium renting machine 200 discriminates whether the supplemental switch 220 is turned on (i.e., whether the supplemental function is activated). Also, with the supplemental switch 220 turned on, the game-medium renting machine 200 allows the operation to proceed to step 52 and with the supplemental switch 220 turned off, the game-medium renting machine 200 allows the operation to proceed to step 53.

In step 52, the game-medium renting machine 200 subtracts a predetermined amount of value from the outstanding balance of the prepaid card as a supplemental-value.

In step 53, the game-medium renting machine 200 subtracts the predetermined amount of value, selected by the player, from the outstanding balance of the prepaid card, as a gaming-ball rental fee and transmits a gaming-ball renting command signal to the gaming machine 100 for renting the number of gaming-balls to the player depending on the gaming-ball rental fee. Also, in step 54, the gaming machine 100 receives the gaming-ball renting command signal from the game-medium renting machine 200.

In step 55, the gaming machine 100 pays out the predetermined number of gaming- balls to the player in response to the received gaming-ball renting command signal.

In step 56, the gaming machine 100 transmits gaming-ball number information generated upon the number of consumed-gaming-balls that are equivalent to a difference between the number of the gaming-balls used for the play and the number of payout-gaming balls that are paid out upon executing the play, to the game-medium renting machine 200. In particular, the gaming machine 100 counts the number of gaming-balls ejected onto a gaming table, while counting the number of gaming-balls paid out upon winning of the gaming-ball succeeded to fit in a winning opening (such as, a regular winning hole or a special winning hole). Further, the gaming machine 100 counts the number of consumed-gaming-balls based on the number of counted gaming-balls, while transmitting consumed-gaming-ball information, related to the number of consumed- gaming-balls, at predetermined timings (for instance every three minutes). In step 57, the game-medium renting machine 200 receives consumed-gaming-ball information.

In step 58, the game-medium renting machine 200 discriminates whether the supplemental switch 220 is turned on (i.e., whether the supplemental function is activated). Also, with the supplemental switch 220 turned on, the game-medium renting machine 200 allows the operation to proceed to step 92 and with the supplemental switch 220 turned off, the operation is routed back to step 50.

In step 59, the game-medium renting machine 200 discriminates whether the number of consumed-gaming-balls reaches a predetermined number of consumed-gaming-balls. Also, if the number of the consumed-gaming-balls reaches the predetermined number of consumed-gaming-balls, the game-medium renting machine 200 allows the operation to proceed to step 60 and if the number of the consumed-gaming-balls does not reach the predetermined number of consumed-gaming-balls, the operation is routed back to step 50.

In step 60, if the predetermined operation is executed on the supplemental switch 220, the game-medium renting machine 200 transmits a gaming-ball payout command signal to the gaming machine 100 for paying out a predetermined number of gaming-balls depending on the amount of value subtracted from the prepaid card as the supplemental-value. Also, the game-medium renting machine 200 stops the activation of the supplemental function.

In step 61, the gaming machine 100 receives the gaming-ball payout command signal from the game-medium renting machine 200. Also, in step 62, the gaming machine 100 pays out the predetermined number of gaming balls to the player based on the received payout gaming-ball payout command signal.

Moreover, while with the second embodiment, the gaming machine 100 has been described as including the pachinko gaming machine, the present invention is not limited such an application and may have an application to a slot machine.

As set forth above, according to the present invention, even if the gaming machine does not have a function to save the player, a game-medium renting machine can be provided which reduces the loss of the player occurring by the plays on the gaming machine.
